QB2430-70 - 70 Amp Circuit Breaker

QB2430-70 - 70 Amp Circuit Breaker

The QB2430-70 circuit breaker is a 70-amp, 3-pole bolt-on breaker used in your electrical systems that require a QB24-type replacement. It is designed for applications where the existing equipment calls for a breaker with matching specifications, including the amp rating, pole configuration, mounting style, and voltage rating.

This circuit breaker has a 240VAC rating and a 10kA A.I.C. rating, making it suitable for your compatible electrical distribution equipment that requires this level of circuit protection. The bolt-on design allows it to be used in systems built for this type of connection. Its compact size also makes it a practical fit for installations where space and breaker dimensions need to match the original component.

For maintenance teams, electricians, and contractors working on existing electrical systems, choosing the correct replacement breaker is important. The QB2430-70 is built for applications where maintaining the original system specifications is the priority.
